About power management (SpeedStep, sleep)

[maddafacca]

hi,

i did everything in here without any errors.

but before that , i applied nullcpupowermanagement.kext , now i did this.

how can i disable nullcpupower ? and how can i be sure that this is actually working?

where should i look to see this intelcpupower is working properly ?

Hi,

just delete NullCPUPM (move to trash), update caches and reboot.

You should get a good score in Geekbench and see P-state changes in HWSensors or SMC Monitor.

hello

i think u must use

imac12,1 or imac12,2 smbios

and must use a proper dsdt

are u OC ?

if so the ssdt must be prepared for that

good hack

hi,

i applied this method. i also patched my AppleIntelcpupowermanagement.kext but it gave kernel panic.

then i used nullcpupowermanagement and ssdts.

i ran GeekBench in 64bit mode. and i got 5900 points.

is it normal ? is my power management working?

when i look hwmonitor , it normally stays at x8 - 800mhz.

when i run geekbench it goes up to x25 - 2500mhz but not 3100mhz. why?

my cpus turbo freq. is 3.1ghz

here is my geekbench results

and i also added screenshot when i was running geekbench test

@maddafacca

hello

use this ssdt and remove nullcpupowermanagement

if u use nullcpu no power management

good hack

[maddafacca]

wow thanks it worked.

how did you do that ? and also it only goes up to x29 - 2.9ghz.

but here it says it can go up to 3.1ghz?

hello

that i don't know , don't have that cpu to test it, googling for a answer...

mac os x is 99% reading, googling, persistency and 1% of luck u hardware be compatible...

good hack

Guys, this topic is really amazing! I used info, reader all, did all what you wrote here, and i got my speed step! Thanks again, fellas, from your russian fan!

[crusher]

Please help from my problem with speedstep fom my GA-Z77X-UD3H and i7 3770k.

Thank you...

And this is my DSDT and SSDT.

hello

first u use a wrong smbios macpro3,1 with ivy cpu ? why ?

good hack

[crusher]

Give me some proposal What do all I need to do for now?

Thanks...

[artur-pt]

hello

try imac13,2

good hack

[crusher]

If you can to look at my DSDT and SDT and that they a little cen?

Thanks!!!!

After in your proposal happens like this......

Small update: Pike has changed ssdtPRGen.sh folder, command to download should now be:

curl -o ssdtPRGen.sh https://raw.github.com/Piker-Alpha/ssdtPRGen.sh/master/ssdtPRGen.sh

Hi all!

I'm trying to align some things in my hackintosh to make it near 100%.

I'm with trouble to enable full power management support. Sleep, hibernation and brightness doesn't work, and some sensors and battery status aren't accurate.

What I'm using:

- a custom DSDT with various patches I grabbed from here (Olarila), here https://github.com/RehabMan/Laptop-DSDT-Patch and here http://pjalm.info/repos/general. The patches were applied with MaciASL. Below a list with the patches applied:

* from Olarila, for Notebook Core i Nehalem: DTGP, EHCI, _T_x rename, LPC (with custom device-id, as described here http://www.tonycrapx86.com/mountain-lion-desktop-support/109371-higher-temps-after-upgrade-10-8-5-a.html#post665445), PNLF SB, IRQS, RTC, SMBUS and HPET;

* from Olarila, from Misc:
 HDEF;

* from RehabMan: [1.1] Fix _PLD Buffer/Package Error and [1.7] Fix *pnp/pnp lower case Error (just to compile DSDT) and [2.12] Rename GFX0 to IGPU;

* from PJALM (General): Basic Apple Device Renames and Intel ESB2 SATA (Orange Icon Fix);

- a custom SSDT, generated with MaciASL;

- a patched AppleIntelCPUPowerManagement, using AICPM patch, as described here http://Olarila.com/forum/viewtopic.php?f=9&t=1003;

- a patched AppleRTC, as described here http://www.insanelymac.com/forum/topic/289798-applertc-patch-cmos-reset-after-sleepwake/;

- ACPIBatteryManager kext, from Rehabman https://github.com/RehabMan/OS-X-ACPI-Battery-Driver;

- ACPIBacklight kext, also from RehabMan https://github.com/RehabMan/OS-X-ACPI-Backlight;

- and Chameleon 2377, SMBios generated by Chameleon and modules also provided with Chameleon, as shown at attached images (ps.: I use "DropSSDT=No" because "Yes" not even boot).

The hackintosh is a Dell Vostro 3500 and were made with unishit and post-install with multishit (before the changes above).

About sleep: when trying to sleep the screen turns off and, when I press a key or click with mouse, it turns on and show the lock screen. At Console nothing about "Wake reason";

About hibernate: when the option to put hard disks to sleep is checked, in System Preferences, the screens goes black and nothing more happens (I'm forced to force shutdown by holding power button);

About brightness: the slider is shown in Displays, in system preferences, but nothing happens when moving it (neither with fn, although the OSD is shown at the screen) - ps.: there are just 3 resolutions to choose (there are more, e.g., when I'm in Linux). I cannot use the Chameleon's VBIOS flag to see if it solves the issue, because the boot screen freezes at certain moment with this option enabled;

About the battery: the status aren't refreshed properly. E.g: when charging, the menubar shows 45% and, then, 50%, doesn't showing the 46, 47, 48, and 49%). Also, some programs report wrong full charge (264% in HWMonitor and 263% in Battery Health, Coconut Battery and, even, Activity Monitor). Battery Diag and iStatsMenus shows correctly.

About Speed Step: does the multipliers in the HWMonitor and the DPCIManager's log (attached) mean that it is working?

About some sensors: the fan isn't recognised and some apps doesn't recognise the CPUs properly. Some chances that is related to power management?

Thank if someone could help. I'm asking here because my skills are very limited, even with a lot of searches over the web.

If some other information are needed or if I'm forgetting something (2:20 AM, I'm sleepy and shivering ) let me know, I'll provide it as soon as I can.

Sorry for my english not so good, my first language is brazilian portuguese.

Thanks in advance!

About screen brightness, you need to patch your DSDT to get ACPIBacklight.kext working. This topic has the needed patches

http://www.insanelymac.com/forum/topic/268219-acpi-backlight-driver/

To get ACPIBatteryManager.kext working you need to patch DSDT too, there are patches for some Dell models here, maybe you can use them as a base for your own patch
